Randy has a girlfriend named Alejandra Genevieve Oaziaza, and has a daughter and two sons. Jermaine (the player) seduced and stole Alejandra from Randy and have two sons with her. So Randy's and Jermaine's kids are cousins AND also half-brothers and half-sister!
So Jermaine is the uncle of Randy's three kids and was their stepfather at one time. lol
